Java字符串加密HMAC-SHA1密钥，转换成Base64编码

新建一个maven测试项目，直接把代码复制过去就行，把data和secretKey的值替换成想加密的值。

package test;
import javax.crypto.Mac;
import javax.crypto.spec.SecretKeySpec;
import java.security.InvalidKeyException;
import java.security.NoSuchAlgorithmException;
import org.Apache.commons.codec.binary.Base64;
public class testP {
    public static string hmacSha1ToBase64(String data, String secretKey) {
        try {
            // 创建一个HMAC-SHA1密钥
            SecretKeySpec signingKey = new SecretKeySpec(secretKey.getBytes(), "HmacSHA1");
            // 获得一个Mac对象
            Mac mac = Mac.getInstance("HmacSHA1");
            mac.init(signingKey);
            // 计算HMAC值
            byte[] rawHmac = mac.doFinal(data.getBytes());
            // 将HMAC值转换成Base64编码
            return Base64.encodeBase64String(rawHmac);
        } catch (InvalidKeyException | NoSuchAlgorithmException e) {
            throw new RuntimeException("获取失败：", e);
        }
    }
    public static void main(String[] args) {
        String data = "值1";
        String secretKey = "值2";
        String encryptedData = hmacSha1ToBase64(data, secretKey);
        System.out.println("HMAC-SHA1加Base64输出成功: " + encryptedData);
    }
}

如果复制过去import org.apache.commons.codec.binary.Base64;标红可以考虑导入依赖
